I tried the ref. Design of iraufamp1,the only change i made is that i used ca3130 istead of lt1220. Slew rate of CA3130 is more than 10times lesser than LT1220.
I used dip lackages for inverter and AND gate. And i wanted to use this design with IR2110. Everything worked fine but IR2110 did not start. VB pin foes not show any voltage.
What problem can it be. Using CA3130 can cause this prob?
Or i made any problem with the inverters?
I made the whole board on bread board so plz don't ask me about schematic and pcb layout..
Need help, any suggestion is highly appreciated.
Regards

It should work if everything else is as per schematic.
Try giving a Audio input signal to start the oscillation, because sometimes it refuses to start on its own.
If not, replace 3130 with TL071 or 356, it works for me.
Driving 2110 or 2113 is not a problem.
Best of luck
